Title: Motor-driven power steering
Inventor: MORISHITA MITSUHARU
IPC: B62D6/00
Filed: 1989-10-03
Abstract: PURPOSE:To prevent a steering wheel from self-rotation by lifting the output voltage of a sub-potentiometer not used directly for control forcibly so as to make error voltage in comparison with the output voltage of a main potentiometer used for control into the fail-safe operation detectable value. CONSTITUTION:When a failure such as leakage is generated, the positive power voltage of potentiometers 3d, 3e is lowered when a leakage current exceeds the feedable current of an arithmetic amplifier 907. When this voltage drop exceeds the forward voltage drop between the base emitters of a transistor 908, a base current flows to the transistor 908 to put it on, and the output voltage of a sub-potentiometer 3d is forcibly lifted up to +5V power so as to generate error voltage exceeding the fail-safe detection level in comparison with the output voltage of the main potentiometer 3d, and thus a microcomputer 902 judges a torque sensor to be abnormal. A fail-safe relay 903 is put off, as well as an electromagnetic clutch 13 and a DC motor 7 are placed in the electrically cut off state.
